(C) because( tourists were exhaling moisture, which had raised the humidity within them to levels such that salt from the stone would crystallize) which引导的非限定性定语从句,作为前句话的补充说明,them在这里很自然就是指代tourists (D) because of moisture that was exhaled by tourists raising the humidity within them to levels so high as to make the salt from the stone crystallize tourists后面跟着raising引起的修饰成分,是修饰tourists,所以them就很自然指代tourists (E) because moisture exhaled by tourists had raised the humidity within them to such levels that salt from the stone was crystallizing 这里them不能指代tourists,因为tourists这个结构exhaled by tourists是moisture的定语,修饰moisture,因此them不能指向tourists;另外because与前面一个句子有紧密的逻辑关系,因此them就是指代第一句话里的Chambers。 -- by 会员 AmyGMAT (2010/5/29 1:10:44)
顶!回答的很好~ 不过我还想问一下,为什么E里面tourists作为moisture的定语来修饰moisture的时候,them就不能指向tourists了?谢谢 |
